title: Comparative effects of indoprofen and indomethacin on rat hypothalamic prostaglandin-synthetase activity.
abstract: The inhibiting effects of indoprofen were compared with those of indomethacin on prostaglandin-synthetase activity in rat hypothalamus. A dose-dependent inhibition of PG-synthetase activity was obtained after intramuscular administration of both antiphlogistic agents; however, indoprofen was found more powerful. In conclusion, the present experiments provide additional evidence against the idea that pyrogen fever is due to the release of PG's of the E type within the hypothalamus since when comparing results obtained with the two antiphlogistic drugs used, no correlation exists between potency in inhibiting PG's synthesis and antipyretic activity.
